One hundred consecutive extraoral open reductions of mandibular fractures were analyzed in an attempt to quantitate the morbidity of this technique and demonstrate possible predisposing factors. A complication rate of 13% was found in this series. Age of the patient, coexisting systemic disease, operative delay and operative and postoperative misadventures could not be correlated with morbidity. An obvious relationship was found between the area of the fracture and the presence and disposition of teeth in the fracture line, and the incidence of complications. Open reductions of the mandibular angle associated with teeth removed from the fracture line produced the greatest incidence of complications both quantitatively and qualitatively.
对100例连续的下颌骨骨折口外切开复位病例进行分析，以量化该技术的发病率，并证明可能的诱发因素。本系列病例的并发症发生率为13%。患者年龄、并存的全身性疾病、手术延迟以及手术中和术后的意外情况与发病率均无相关性。发现骨折部位与骨折线上牙齿的存在和分布以及并发症的发生率之间存在明显关系。下颌角切开复位且骨折线上的牙齿已拔除的情况，无论在数量上还是质量上，并发症的发生率都是最高的。
